This Part replaces GB/T 19267.6-2003 "criminal and chemical examination of trace evidence in Part 6: Scanning Electron Microscopy Mirror method. " This portion of the GB/T 19267.6-2003 compared to the main changes are.

--- Standard name a "scanning electron microscopy/X-ray spectroscopy";

--- Increasing the term of the environmental electron microscope (this section 3.2,3.18);

--- Increasing the principle part of the environmental electron microscope (this section 4.1);

--- Instrument composed of indicators made the necessary changes (this part of GB/T 19267.6-2003 and Chapter 5 of);

--- Modify the content of the samples prepared (this section 6.4.1,6.4.2, GB/T 19267.6-2003 of 6.3, 6.4);

--- Increased working distance describes the content (in this section 7.2.4);

--- Modify the sample analysis of the content (in this section and GB/T 19267.6-2003 7.3).
